Abstract

The environment is changing rapidly, and considerable research is aimed at understanding the capacity of organisms to respond. Changes in environmental temperature are particularly concerning as most animals are ectothermic, with temperature considered a key factor governing their ecology, biogeography, behaviour and physiology. The ability of ectotherms to persist in an increasingly warm, variable, and unpredictable future will depend on their nutritional status. Nutritional resources (e.g. food availability, quality, options) vary across space and time and in response to environmental change, but animals also have the capacity to alter how much they eat and what they eat, which may help them improve their performance under climate change. In this review, we discuss the state of knowledge in the intersection between animal nutrition and temperature. We take a mechanistic approach to describe nutrients (i.e. broad macronutrients, specific lipids, and micronutrients) that may impact thermal performance and discuss what is currently known about their role in ectotherm thermal plasticity, thermoregulatory behaviour, diet preference, and thermal tolerance. We finish by describing how this topic can inform ectotherm biogeography, behaviour, and aquaculture research.

饮食对体外热能的影响
环境正在迅速变化,大量研究旨在了解生物的应对能力。环境温度的变化尤其令人担忧,因为大多数动物都是外温动物,温度被认为是影响其生态学、生物地理学、行为学和生理学的关键因素。外温动物能否在日益温暖、多变和不可预测的未来生存下去,将取决于它们的营养状况。营养资源(如食物的可获得性、质量、选择)因时空和环境变化而变化,但动物也有能力改变它们的进食量和进食内容,这可能有助于它们改善在气候变化下的表现。在这篇综述中,我们将讨论动物营养与温度之间相互关系的知识现状。我们采用机理方法来描述可能影响热性能的营养物质(即广义的宏量营养素、特定脂质和微量营养素),并讨论目前已知的营养物质在外温动物热可塑性、体温调节行为、饮食偏好和热耐受性中的作用。最后,我们将介绍这一主题如何为外温动物的生物地理学、行为学和水产养殖研究提供信息。

期刊介绍: Biological Reviews is a scientific journal that covers a wide range of topics in the biological sciences. It publishes several review articles per issue, which are aimed at both non-specialist biologists and researchers in the field. The articles are scholarly and include extensive bibliographies. Authors are instructed to be aware of the diverse readership and write their articles accordingly. The reviews in Biological Reviews serve as comprehensive introductions to specific fields, presenting the current state of the art and highlighting gaps in knowledge. Each article can be up to 20,000 words long and includes an abstract, a thorough introduction, and a statement of conclusions. The journal focuses on publishing synthetic reviews, which are based on existing literature and address important biological questions. These reviews are interesting to a broad readership and are timely, often related to fast-moving fields or new discoveries. A key aspect of a synthetic review is that it goes beyond simply compiling information and instead analyzes the collected data to create a new theoretical or conceptual framework that can significantly impact the field. Biological Reviews is abstracted and indexed in various databases, including Abstracts on Hygiene & Communicable Diseases, Academic Search, AgBiotech News & Information, AgBiotechNet, AGRICOLA Database, GeoRef, Global Health, SCOPUS, Weed Abstracts, and Reaction Citation Index, among others.
